When cells have been stimulated with Wnt, catenin was recruited by membrane adherens junctions and accumulated inside the nucleus (Fig 9). When cells were pretreated using the chosen RPMI 1640, repelleted, resuspended in serumfree RPMI 1640 and plated at a density compounds catenin redistribution was inhibited. This effect was nicely apreciated in Inhibitors n, n and n (Fig 9). In addition, levels of catenin in Inhibitor ntreated cells virtually desappeared (Fig 9). As seen in the Figs 8 and 9, the selected cancer chemotherapeutic agents were capable to effect each the subcellular redistribution as well as the activity of catenin as they have been capable to inhibit its nuclearcytoplasmic shuttling and its recruitment at plasma membrane as well as the expression of its target gene CyclinD1. The Inhibitors n, n and n were the most powerful. Notably, the compounds that inhibited each Akt and catenin had the greatest effect on cell viability supporting the idea that dual inhibitor of the Akt/mTOR pathway and catenin may result in a potent antiproliferative effect against human prostate cancer PC3 cells, although the putative influence in the compounds in other signaling pathways is not ruled out. Consequently, immediately after applying various models developed by Molecular Topology method, six compounds has been chosen as potential cancer chemotherapeutic agents. Soon after in vitro study whether or not they inhibit Akt, mTOR, catenin and/or Cyclin D1 at diverse times of incubation; we are able to affirm that five out of these six compounds (see Fig 10) inhibit at the very least one of the studiedPDOI:ten.1371/journal.pone.0124244 April 24,17 /Dual Akt and BetaCatenin Inhibitors by Molecular TopologyFig 7.

We can also state that these 5 compounds influence PC3 cell viability with unique potency. And, we can remark also that Inhibitor n also decrease cell viability on HT29 cell line. Finally, we can confirm that this five selected compounds could be utilized as cancer agents interacting with Akt/mTOR and Wnt/catenin pathways in colorectal and prostate human cancer cell lines. Despite the fact that it is evident that complex properties, including inhibition of Akt or catenin, cannot be discussed in such easy "structural" terms, thanks to the QSAR study final results, some interesting consequences is often pointed out. Hence, in equations DF1 to DF4, you'll find indices more or much less explicitly associated to the existence of high conjugation (as as an example EEig11r, piPC02 or SCBO).
